SB Acoustics SB15CRC30-4 5" Woven Carbon Fiber Cone Woofer - 4 ohm

SB Acoustics SB15CRC30-4 5" Woven Carbon Fiber Cone Woofer - 150mm- 4 ohm

Woven carbon fiber cone and other advanced features provide a rigid piston and fast transient response. Lightweight rigidity + controlled damping = a combination of immediacy, detail, dynamics, and tone.

Low Q, looks good for small vented box. Could be used 2way with low Fs tweeter.

• Rohacell®/Carbon fibre sandwich cone for optimized stiffness/damping ratio
• Vented cast aluminum chassis for optimum strength and low compression
• Low damping rubber surround for improved transient response
• Non-conducting fibre glass voice coil former for minimum damping
• Extended copper sleeve on pole piece for low inductance and low distortion
• CCAW voice coil for reduced moving mass
• Long life silver lead wires
• Vented pole piece for reduced compression

Some box suggestions:

4 liters sealed, Qtc .5 F3 103Hz

10 liters vented 1.5" x 7.8" Fb 39Hz / F3 50 Hz
